An uninstaller for ClickOnce applications

A .NET library to programmatically uninstall ClickOnce-deployed applications — silently, without the interactive "Maintenance" dialog.

Why?

Apparently, ClickOnce installations can't be removed silently. The ClickOnce uninstaller always shows a "Maintenance" dialog, requiring user interaction.

For Wunderlist 2.1 the original authors wanted to switch from a ClickOnce deployment to a Windows Installer package using the WiX Toolset. They wanted this switch to be integrated into the new installer, invisible to the user.

What?

ClickOnceUninstaller imitates the actions performed by the ClickOnce uninstaller, removing files, registry entries, start menu and desktop links for a given application.

It automatically resolves dependencies between installed components and removes all of the application's components which are not required by other installed ClickOnce applications.

Requirements

Windows only. The library reads and writes ClickOnce registry keys under HKEY_CURRENT_USER and uses Windows-specific ClickOnce/System.Security.Policy APIs.
Targets .NET Framework 4.8 (it cannot target .NET Core / .NET 5+ because of the ClickOnce APIs it depends on).

Install

dotnet add package ClickOnceUninstaller

or, from the Package Manager Console:

Install-Package ClickOnceUninstaller

How?

using ClickOnceUninstaller;

// Look the application up by its display name (as shown in "Apps & features")
var uninstallInfo = UninstallInfo.FindByName("Application Name");
if (uninstallInfo != null)
{
    var uninstaller = new Uninstaller();
    uninstaller.Uninstall(uninstallInfo);
}

Other ways to locate an installed application:

// By the update URL of the ClickOnce deployment
var byUrl = UninstallInfo.FindByUpdateUrl("https://example.com/app/App.application");

// Enumerate every installed ClickOnce application
foreach (var info in UninstallInfo.FindAll())
{
    Console.WriteLine($"{info.Name} {info.Version} — {info.Publisher}");
}
